Decarbonizing the industrial sector, and the energy sector in particular, is a major strategic challenge for the ecological transition, energy sovereignty, and industrial competitiveness in France and the European Union. Energy production, transformation, storage, and distribution activities account for a significant part of greenhouse gas emissions, due to the historical use of fossil fuels, complex industrial processes, and heavy infrastructure with long life cycles. The European Green Deal, launched in 2019, sets the goal of carbon neutrality by 2050, with an intermediate target of reducing greenhouse gas emissions by at least 50% or even 55% by 2030. For the energy sector, these ambitions result in a deep transformation of industrial models, incorporating the massive development of low-carbon energies, the optimization of existing infrastructure, and the reduction of direct and indirect emissions across the entire energy value chain. This green deal invests in innovation, clean technologies, and green infrastructure. The European regulatory framework has been significantly strengthened with the “Fit for 55” package, the revision of the Emissions Trading System (EU ETS), the gradual extension of carbon pricing, and the implementation of the Carbon Border Adjustment Mechanism (CBAM). These developments encourage industrial energy players to accelerate their investments in technological solutions to reduce their carbon footprint in a sustainable manner while remaining competitive in an increased international competition. The transformation of the energy sector is taking place within significant economic, technological, and geopolitical constraints. In this context, technology and deep tech startups have a strategic position by providing disruptive solutions that complement the engineering and deployment capabilities of large industrial energy groups. Their ability to experiment quickly, propose new technological and economic models, and accelerate scaling up is a key factor in the success of the energy transition. Drawing on the expertise of the EVOLEN' UP program sponsors, this call for projects on decarbonization in the energy sector is part of a startup/large group collaboration initiative that aims to accelerate the emergence, demonstration, and deployment of innovative technologies. Without being exhaustive, this call is open to all startups likely to provide disruptive solutions on the following topics: • Decarbonization of industrial energy operations • Industrial performance, operational excellence • Process improvement, asset management, aging asset management • Energy efficiency, reduction and optimization of energy consumption • Reuse and energy synergies • Energy recovery from various sources: solar, light, electromagnetic, radio frequency, heat, movement, vibration, etc. • Carbon capture, use, and storage (CCUS) • Reduction of greenhouse gas emissions (e.g., CO₂, CH₄) • Gas separation and treatment • Integration of renewable energies into oil/gas operations • Electrification of operations/processes • Use of low-carbon fuels in operations • Circular economic practices • Life Cycle Analysis (LCA)
